So much for Linus's time away to work on himself. It's disheartening to see how hard it is to change even when someone has the intention and resources to.

I would say this demonstrates inadequate progress.
As a manager, if I had a report who exhibited this level of verbal aggression, we would have a talk, and if it happened again, we'd be going through HR. It's not acceptable, regardless of technical merit.
